Waste from milk factories and breweries could be put to good use in fighting climate change, according to scientists at Green Fuels Research.
The Gloucestershire-based company in the UK has won funding under the Department for Business, Energy and Industrial Strategy’s Biomass Feedstocks Innovation Programme for its Microalgae Biomass Sustainability project (MISTY).
The project aims to boost yields from algae farming in the UK by co-culturing microalgae with bacteria, using wastewater from the brewing and dairy industries.
The key innovation lies in cultivating microalgal strains in conditions adapted to the UK’s weather by using two bioreactor systems, one taking advantage of natural sunlight during spring and summer and the second using organic compounds present in dairy and brewery wastewater as carbon sources in winter.
MISTY will enable breweries and the dairy sector to dispose of zero-value, environmentally harmful waste streams while sustainably industrialising a high-value bioenergy resource, decarbonising their value chains and combating climate change.
”Importantly, the MISTY process doesn’t use drinking-quality water or compete for land with food production,” said Green Fuels chief strategy officer Paul Hilditch, “while promising to increase the UK’s strategic biomass supply.” Equally important, by promoting carbon capture, MISTY aligns itself with the Green Industrial Revolution and accelerates the UK’s path to achieving net-zero carbon emissions by 2050.
Green Fuels is working with Wadworth & Co, an independent regional family brewer and pub company, operating in excess of 150 pubs and brewing beer in the market town of Devizes since 1875.
